Modern Hard disks come integrated with a controlling circuit, called Logic Board, which is responsible for supplying power and controlling hard disk internals. Also denoted as controller board or hard disk PCB, this intelligent circuit board is consisted of all control, sense, amplification and conversion circuitry that make a hard disk to operate. Thus, when a hard disk logic board suffers malfunction, there develops high odds that you loose data. For data restoration, it is required that you should have valid data backup. But in case of any backup issues, you need to seek technical assistance from Hard Drive Recovery experts.
When a power surge or voltage spike takes place, it is most likely that it will affect hard disk circuit board. Thus, it acts like the weakest spot to fail during such incidents. When on one side, it prevents the extra current to flow inside the drive that could cause unrecoverable damages; the other side is harshening too. A hard disk cannot get power and start without a healthy logic board. It simply implies that hard disk platters don’t rotate underneath the copper wire, leading to inaccessibility of stored data.
A hard drive logic board is basically consisted of below given components:
1. Control circuitry: It is comprised of internal memory and microprocessor that perform tasks like controlling movements of read/write heads, spindle motor, actuator etc., managing geometry translation, and other such.
2. Sense, amplification, and conversion circuits: These circuits allow accepting, amplifying, and interpreting low-voltage signals.
3. Interface: It is the interface that runs between the disk and other parts of the system.
4. Firmware: This is the software routine, embedded into read-only memory that makes a hard drive work.
If one or more of the above components fail, a logic board fails to function. It’s very infrequent that you can just swap it and get the lost data back; also it is very risky to do. Thus, in order to get safe recovery, you should consult a reputed Hard Drive Data Recovery company. Such companies have Hard Drive Recovery experts who deploy advanced techniques to deal with such failed hard drives. They make repairs and replacements of damaged hard drive internals and perform refined steps in safe surroundings of Clean Rooms.
